  • Page 101: Land Wheel

    Adjustments 12.17 Land wheel 12.17.1 General The land wheel (1) is part of the standard scope of delivery of implements for on-land ploughing. During turning, gravitational force causes the wheel to turn away from the stop (2) to the opposite working position. A return spring (4) then turns the land wheel back to the working position against the counter stop (3).

  • Page 102: Setting The Return Spring

    Adjustments 12.17.2 Setting the return spring If the land wheel does not turn correctly, the problem can be solved by adjusting the return spring (4) as follows: • Land wheel not turning back to working position => − Increase the spring force of the return spring (4) by turning the adjusting screw (5) clockwise.

    Overload safety devices 13.2.2 Setting the release force Different operating pressures can be set using the hydraulic overload safety de- vice: choose a low operating pressure for shallow and light soil conditions and a higher operating pressure for heavy soil conditions. There is a shut-off valve (1) underneath the pressure gauge (2).

    Overload safety devices 13.2.3 Depressurising the hydraulic system Always depressurise the hydraulic system before performing maintenance or re- pair work, for instance. To do so, pressure must be released via the spool valve of the depth wheel as follows. Risk of injury due to incorrectly performed maintenance work DANGER Incorrect maintenance and repair work jeopardise operational safety.
